SPECIFICATION forming part of Letters Patent No. 515,373, dated February27. 1894.

Application iiled September 25, 1893. Serial No. 486,440. (No model) To@ZZ whom it may concern.-

Be it known that I, PLIN C. SOUTHWICK, a citizen of the United States,residing at Sandwich, in the county of De Kalb and State of Illinois,have invented certain new and useful Improvements 'in Ealing-Presses,which are fully set forth in the following specication, reference beinghad to the accompanying drawings, in which- Figure 1 represents a sideelevation of the front end of a press embodying my invention; Fig. 2, across-section thereof taken on the broken line 2. 2 of Fig. 1, with themiddle p0rtion broken away; Fig. 3, a detail inverted plan taken onthebroken line 3. 3 of Fig. 1, with the central portion also brokenaway; Fig. 4, a bottom plan of thesignal device detached; Fig. 5, adetail end elevation of one of the followers, the lower portion beingbroken away; Fig. 6, a plan View of the cam portion of the power, thesweep and top cross-beam being removed; Fig. 7, a vertical section takenon the line 7. 7 of Fig. 6; Fig. 8, a detail plan of one end of the camand the cable attachment thereto; Fig. 9, a plan of the catch or blockwhich connects the cable to the cam, detached from the cam; and Fig. 10,an edge elevation of the same.

Myinvention relates to power baling-presses of a general type wellknown, and particularly such as shown in my prior Letters Patent No.458,641, dated `September 1, 1891, and No. 473,645, dated April 26,1892.

The present invention relates to -the signaling device which indicatesthe point for the application of a new follower for the formation ofanother bale, and to certain devices for strengthening and supportingthe cam o'perating mechanism by which the compressing force is appliedto the formation of the bales. The signaling device is an improvementupon the one shown in my iirst named patent, N o. 458,641, and the camoperating devices are an improvement upon those shown in the saidpatent, and also my second patent, No. 473,645.

In the drawings, A represents the pressframe, which is of ordinaryconstruction, the same as shown and described in my patent,

No. 458,641, and usually mounted on wheels.

.As well known, this structure is practically a long chute, which isclosed at all sides a portion of the way to provide a chamber withinwhich the material is compressed, while for the remainder ot' its lengthit is open at the sides and preferably tapers slightly from the rear endot' the chamber to the rear or discharge end ofthe chute. In thedrawings only a portion of this press is shown, all the front portionbeing broken away and only the rear end and a portion of the chamber, a,being shown. It will be understood, of course, that the hay, or otherlike material, which is to be formed into bales, is compressed by afollower within the closed chamber, which may be called the compressionchamber. The bales are formed successively and continually as thematerial is supplied to the press, and it is evident that it isdesirable to have some signal which shall indicate when a bale' ot' therequired size has been formed, So that a new follower can be introducedto mark the beginning of a new bale. As stated in my patent, No.458,641, it is desirable that this signal should be given whenthefollower at the forward end of a bale passes out from the rear ordischarge end of the compression chamber, and my invention, so far asthis part of the machine is concerned, relates to this signaling device.

A plate, B, is secured to the under side of one ot' the side-beams, a',of the press-frame, A, being located justin rear of the closedcompression chamber, as seen in Fig. 1. This plate is provided withslots, b, at opposite edges running lengthwise of the plate, and issecured to the beam by means of screw-bolts,

b', passing through the slots into the beam, I

thusproviding for the adjustment of the plate lengthwise of the press soas to locate the signal accurately at the point desired. At the frontend of this plate a gong or bell,G, is secured to the outer edgethereof, as seen in Figs. 1 and 4. The hammer, D, is in the shape of abell-crank lever, one arm, d, of which is mounted lengthwise of theplate in a keeper, d', fastened to the plate and having a tubularopening in which this arm is placed and through which it is free toslide back and forth lengthwise of the plate. The other arm,

d2, of this bell-crank projects directly outward IOO transversely of theplate until it reaches the plane of the bell, and terminates in a smallknob or ball adapted to strike the bell upon proper movement thereof.The end of the horizontal arm is extended through the keeper andprojects beyond the same toward the front end of the press, as seen inFigs. 3 and 4. A spring coil, cl3, is arranged upon this extension ofthearm outside the keeper, being held thereon by a nut, d4, threaded on theextremity of the arm. A dog or catch, E, is hinged at one end to thissliding hammer, this connection, as shown in the drawings, being at thejunction of the two arms. The body of the dog is straight and isextended Outward or rearward. along the plate and ter-` minates inakindof straight hook, e, bent so as to extend inward transversely of theplate andnormallyprojectingbeyond theinner edge thereof, thus forming akind of finger extending straight inward at this inner edge of theplatel Between this hook end and the pivot of this dog there isan,extension,e,on theinner edge of the straight body. This projectionispbeveled or inclined along the edge next to the hook, as seen in thedrawings, and as here shown it is also similarly beveled or inclined atthe opposite edge, thus presenting a V; shaped lug projecting inwardfrom the body of the dog; this bevel of the edge next to the hinge isnot necessary, however, while the inclination of theopposite edge isnecessary to the working of this device as here designed. A spring,e2,is fixed at one end near the outer edge of the plate,its free endbeing arranged to actk upon the back of the dog near the outer end ofthevlatter, this action being nornially to force the dog inward to its.fullest extent so that the finger at the end thereof will projectbeyond the inner edge of the plate, as seen in Fig 4. A stop-block, es,is secured to the plate at the inner edge .thereof inside of thedog andjust in front of the lug thereon. vIts inner edge is beveled or inclinedat the front end thereof so as to present an inclined face or wayadapted, to fit the front or outer inclination of the lug on the dogwhen the latteris in normal position of restas seen in Fig. 4, in whichposition it is held against this cam-stop by the action of thespringback of the dog. A buttonlatch, e4, is pivoted to, the plate near therear end thereof and is adapted to swing over the finger of the dog,being bent for this purposey as seenin Figs. l and 4. This device,therefore, serves as a ykind of keeper to hold up the outer end of thedog in .proper position against the plate, as seen in Figs. l and 4while it may be turned back at any time for removal o r repairs ofparts, as maybe required. The followers, F, are of ordinaryconstruction, except .that a shallow recess or short groove,'f, is sunkin each end, f', close to the upper edge of the follower, as seen inFigs. l and 5. This recess on the end next to the signal will be in thesame plane with the finger of the hammer dog, so that under the actionof the spring at the back of the latter the finger will be thrust inwardinto the recess unless some obstruction prevents. The recesses orgrooves are proportioned so that their length, extending crosswise ofthe end edges of the followers, will be somewhat greatery than the widthof the lfingerv on the dog, so that this finger may have a limited freemovement in the recess. The recesses or grooves are provided in each endof the followers, so that no special care is required in placing afollower in the press, except that recesses shall be at the Lipper edgethereof; whichever end comes on the signal side of the press, there willbe a recess for the reception of the finger'on the dog.

The power mechanism, `by which lthe vcompression of the material in' the.press is effected, is practically the same as shown and described in mypatent, No. 473,645,1except in a few particulars, and will l'requireonly brief mention here except where the improvef ments have beenv made.There are here shown in Figs. 6, 7 and 8, a grooved cam, G, sliding bar,H, cam, I, and chain-cable, J ,substantially identicalin constructionand operation with the corresponding parts shown and described in mysaid patent. The cam, G, is provided with a peripheral T-shaped groove,g,and is fastened to the sweep-shaft, g', asin the former case, and itsrotationis effected by meansof the usual sweep, which, however, is notshown in the drawings. The sliding-bar, I-I, vis also j mounted so as tobe carried by the cam,'as rin, my former patent, and the` cam itselfisprovided with slots or apertures, g2, in its rim at diagonally oppositecorners ther,eof,into either of which either end, h, of the bar'may be,thrust to engage with a block, K, mounted loosely 011 the peripheryofthe cam by meansof the groove therein. Thebar is also provided at eachend 'withan anti-friction roller, hwhich is engaged by the cam, I, tooperate the sliding bar 'the same as in my former .patent,-.except thatthe rollers are a little larger than there shown. vThe block, K, isattached to the cam by means of side-pins, k, at its inner end which fitinto and` runin the T-head of` the groove,

:so that the block freely slidesupon the cam `except when stopped by theprotruding ends' of the sliding bar. But the construction of this blockis different' from .that shown in Patent No. 473,645.

In the block there shown a notch is cut inthe inner edge thereof, justin front of the pins for the reception ,of the `en ds of the slidingbar, and the cable is at'- itached to the extreme outer end of: theblock. :In operation the strain upon thisblock is very great, as must beobvious to. any one familiar with the-action of these lnachines, and

under this strain the block will sometimes break at the back portion ofthe notch next to the pin, this being the weak place in the block onwhich the .greatest leverage `is brought, because of thepointat whichthe cable is attached and also the outside shoulder of thefnotch bearingupon the outside of IOS IIO

. in the former case. In addition to this change I also provide for theattachment of the cable y at the rear end of the block by providing anaperture, k2, outside and back of the connectingpins, through which oneof the links, Z, of the power-cable, L, is passed, as seen in Figs. 8and 9. Now, this makes'nearly a straight pull forward, against the endof the sliding bar when it locks the block, instead of a kind ofdownward pull across the end of the said bar,

and so the danger of breaking the block across the bar is practicallyremoved. This block is also constructed with a kind of tongue, k3, atthe forward end thereof. This tongue is formed by cutting out the freearm on the inside at its outer end so as to make a bend, and thisportion is .also fiattened or spread out laterallyso as to form a kindof lip extending out over the `inner link, Z, on each side, as seen inFigs. 9 and l0. This projecting tongue serves to hold the link to theperiphery of the cam during the sliding movement of the block, and sokeeps the link and the cable of, which it forms a part in properposition on the cam.

- The strain upon the locking end of the sliding bar, as the cam isturned to operate the compressing devices, is, of course, very great,and I have found that Withou't'some supplementary'support the bar willspring, and, in fact, is in danger of breaking. Anoutside support is,therefore, provided` for the ends of the bar in the shape of astoparm,l\l, pivoted to the inside of the cam-rim at each end of thesliding lever, but arranged on opposite sides of the latter, the pivotat each end being on the side opposite to the contact surface of thebar, as seen in Figs. 6 and 8. The outer end of this pivoted stop-'armis rounded in the direction of itswidth so as to present a circularhead, m, and about the center thereof there is a short projecting tip orlug, m. In opposite edges of the sliding bar,near the respective endsthereof, there are provided notches,h2, which are adapted to ref eivethe projecting tips, m', of the respective stop-arms. As one end of thissliding bar is driven outward by the actuating cam, I, the stop-armvibratcs upon its pivot, its circular end in contact with the edge ofthe bar permitting this movement, and the parts are so arranged that asthe bar reaches the limit of its outward thrust the stop arm will bestraightened, or in other words will stand about perpendicular to thebar, as seen in Fig. 8. This arm, therefore, in this position forms aperfectly rigid stop or resistance to the outward spring of the lockingend of the bar, thus preventing any movement whatever of the said barand avoiding all danger of breakage. Obviously these pivotedresistance-arms afford no obstacle to the free sliding of the bar, astheir circular ends rock easily on the edges of the bar, and so offer nofrictional resistance to the reciprocation of the latter.

In operation the action of the signal device is as follows: From thedescription above it will be seen that the recesses or grooves in thefollowers are in the same plane with the hinged dog on the hammer, and,therefore, when a follower is brought opposite the finger of the dog itwill be forced inward under the action of its spring, the finger passinginto the recess. Now, suppose the device to be in this position,theforward movementof the follower Will pull the dog forward so long as thefinger remains in the groove, thereby drawing out the horizontal arm ofthe hammerv and compressing the spring back of the keeper. In thismovement it is obvious that the forward incline of the lugon the dogmust ride upon the incline of the stop-block, which will have the effectto swing the dog outward on its pivot and against its spring, as it ispulled forward, until finally the finger is entirely freed from thegroove in the follower. As soon as the finger is entirely cleared fromthe follower there is no longer any substantial resistance to theretracting spring, and the latter with its full force quickly draws backthe hammer, thereby bringing it up sharply against the bell and makingthe required signal, which indicates that it is time for anotherfollower to be put in place, andthe machineis stopped long enough forthis purpose. The dogis, of course, drawn back with the hammer duringthis movement and is so held until another follower reaches it, the dogbeing kept swung outward by the action of the hardly compressed hay orother material as it passes by the dog-finger. It will be noticed thatlthis finger is rounded or beveled at its extremity so that thecompressed material passes by'it more readily and there is less tendencyof the dog to engage therewith, and, further, the spring at the back ofthe dog is not sufficiently strong to compel an engagement of the fingerwith the material, as it passes by, sufficient to drag the dog forwardagain and make a new signal; the retracting spring is so much strongerthan this back spring that it prevents any such action. As soon,however, as another follower reaches the dog, the finger of the latteris at once forced into the recess in the follower and the signal isrepeated.

In the power devices the cam is rotated the same as in my prior patent,and the sliding block is engaged by the projecting end of the slidingbar, thereby temporarily securing the block to the cam, and so windingthe cable upon the cam to produce the required action of the compressingdevices. At the half turn of the cam the block is released by the slid-IOO IIO

ing of the bar in the opposite direction under the influence of theVcam, Land theblock then slips back on the cam until it is engaged by theother end of the sliding 'bar-,Which in the mean time has beenprojected. The action of the stop-arinsin resisting the strain upon thesliding barbas already been eX- plained, and also `the effect of theparticular construction of the sliding block and the attachment theretoof' the cable. No further explanation of the operation of these devicesis required.
